I am also currently waiting for full hd projectors to become cheaper or with led technique as I would burn down the lamps in half a year with my gaming amount!
I would like to built a 3 projector curved display with no bezels, but is currently too expensive. A hd ready resolution wouldn't come into my house,, because I do not get the wished vertical and horizontal resolution, that I would like to have (except I would drive 6 projectors
).
This is interesting when it comes to led technique, high hz, perhaps 3d and full hd. But currently not affordable.
